«the 11-member team, working far from base and lacking air support, was ambushed by more than 100 militants aligned with the Islamic State after superior officers twice changed its mission to one that carried far greater risks.

….

Instead, Lt. Col. David Painter, a battalion commander based in Chad, ordered Captain Perozeni’s team to continue. Investigators later concluded that Colonel Painter and other senior officers failed to assess the risk of sending the ill-prepared team on such a hazardous mission, according to the redacted report that identified Colonel Painter by his title, but not by name.

Colonel Painter’s order failed to take into account that Captain Perozeni’s team had gone “nearly 24 hours with little rest,” had no reinforcements standing by if danger struck and had no plan to evacuate wounded troops under fire, according to the redacted report.

Colonel Painter was ultimately punished for improperly overseeing predeployment training. But two military officials on Wednesday said he is expected to be promoted to the rank of full colonel in the coming months.»
